A TTORNEY Ua ed S s Peter"? I 2,829,816 DISPLAY DEVICES William E. Jason, Redwood City, calir. Application July 26, 1956, Serial No. 600,246 s Claims. (Cl. 229-23 This invention relates to improvements in display devices of the type comprising a display panel surrounded by a decorative frame of triangular cross-section and constructed of paperboard. The invention has particular application to the construction of display devices of the aforementioned type in large dimensions of the order of several feet in height and an even greater dimension in length, presenting problems of weight, rigidity, stability, assembly, and transportation.

The present invention provides an improved display device which is constructed from single-faced corrugated board and can be stored and shipped in rolled up condition, and which is so constructed that the corrugations of the board provide rigidity in one direction and the folded panels provide rigidity at right angles thereto. Advantage is taken of the decorative appearance inherent in corrugated board and the frame is so constructed that its corrugations extend at right angles to the frame portions of the display device.

Display devices embodying the present invention are readily adaptable to different sizes in that their total length may be reduced to than available space simply by trimming-one of its constituent blanks along one edge by a straight out without impairing thepan'el or corner construction of the device, or its assembly.

The improved-display device is composed of three separate blanks, a main blank from which the main por tion isconstructed and two identical blanks from which the ,end'structures are assembled. This basic form of construction is known in display devices of this general types, The invention provides improvements of this basic form of construction by reason of whichthe display device -is more readily assembled, and after assembly provides an attractive and decorative structure of greater strength and rigidity than provided by known forms of construction, light weight, strength and rigidity being important in large-size displays measuring several feet in length.

These and other objects, features'and advantages of the invention will appear more fully from the detailed description which follows accompanied by drawings showing', for the purpose of illustration, a preferred embodiment of the invention. The invention also resides in certain new and original features of construction and combination of elements hereinafter set forth and claimed.

In the following description and in the claims various details will be identified by specific names for convenience. These names, however, are intended to be generic in their application. Cor-responding reference characters refer to corresponding parts in the several figures of the dawings.

The drawings accompanying, and forming part of, this specification disclose certain specific details of the invention, but it is understood that the details may be modified in various respects without departure from the principles of the invention and that the invention may be applied to other structures than the one shown.

. The main blank A consists of a rectangular sheet of I single-faced corrugated board, the corrugations extend- I appearance, the corrugations extending at right angles 13 and 14 articulated to the main panel 12 along outer side fold lines 15 and 16. Inner side panels 17 and 18' are articulated to the outer side panels along ridge fold lines 19 and 20, and inner bottom panels 21 and 22 are articulated to the inner side panels 17 and 18 along inner side fold lines 23 and 24.

The outer and inner side panels and the inner bottom panels are so dimensioned as to produce a frame structure of triangular cross-section by folding as shown in Figure 1. In this position the outer side panels 13 and 1 4 are upright, the inner side wall panels 17 and 18 slope inwardly towards the main display panel 12, and the inner bottom panels 21 and 22 lie underneath the inner side wall panels, preferably with their terminal edges in abutment with the outer side panels 13 and 14.

The end edges 25 and 26 of the main blank A are straight and extend in line with the corrugations. Markings 27 and 28 may be imprinted on the main panel 12 at appropriate distances from the end edge-s as a guide for shortening the total length L of the main panel to a reduced length 'l as indicated in Figure 2. This may be complemented by an appropriate layout of the decorative subject matter, as will be described further below.

Thedecorative subject matter or the advertising mes sage may be printed on either the face ply or on the corrugated ply. Detailed subject matter such as lithographic work is preferably printed on the face ply in which event the frame surrounding it has a corrugated to the frame structure provided by the several side panels. It is also possible to print an advertising message accompanied by stylized illustrations on the corrugated ply in which event the frame appears smooth and provides a contrast. If desired, the face ply may also be printed to provide an appropriate color scheme with the message on the main panel.

The main blank A is delivered pre scored to the user and may be shipped and stored in rolled condition as' shown in Figure 10. After unrolling of the blank andfolding of the blank along the several side fold lines, the main portion of the display structure becomes a substantially rigid structure, the corrugations providing rigidity in the direction 11 and the triangular frame structures providing rigidity at right angles thereto.

After folding of the side walls, the inner bottom panels are secured to the main display panel by suitable means,

for example by conventional pronged clips 29 shown in Figure 8. The main structure of the display device is.

then turnedrupside down as shown in Figure 2 and the inner bottom panels may be additionally secured to the main panel 12 by further fastening devices which may have the form of the pin clip 30 shown in Figure 9.

The pin clip 30 comprises a substantially straight shank portion 31 and a curved clip portion 32 extending from the end of the shank portion suficiently far to extend across and beyond the shank portion at 33, thus forming substantially the letter F. The shank portion extends through the main panel 12 into the corrugations of the inner bottom panels 21 and 22 and the clip portion 33 tends to draw the secured panel portions together, whereby a secure connection is provided without the use of adhesives.

The end blanks which form the end portions of the frame are of identical shape and may be produced by the same cutting and creasing die. A flat end B is shown inFigure 3. It is cut from single-faced corrugated board and comprises an inner bottom fiat 34, an inner end wall panel 35, an outer end wall panel 36, and an outer bottom flap 37. These flaps and panels are articulated to one another along fold lines 38, 39 and 40. The fold lines extend transverse to the corrugations as shown and the end blanks may be rolled for shipment and storage, together with the main blank, preferably near the center of the roll.

The blank B further comprises a pair of securing flaps 41 and 42 articulated to the inner end wall panel 35 along oblique fold hues 43 and 44. Side flaps 45 and 46 may be articulated to the outer end wall panel 36 along fold lines 47 and 48 extending in line with the corrugations.

The assembly of the end structures may proceed as follows. The blank B is lowered onto the erected main structure substantially as shown in Figures 3 and 4 and the inner bottom flap is attached to the main panel 12 by means of pronged clips 29. The securing flaps 41 and 42 are folded over the inner side panels 17 and 18 and also secured thereto by further pronged clips 29. In secured position the flaps 41 and 42 reinforce the corners of the display device and make the corners rigid.

After securing of the flaps 41 and 42 the inner end panel 35 assumes its proper slope with respect to the main panel 12 and it is only necessary to fold the outer end panels 36 into vertical position while also inserting the side flaps 45 and 46 into the hollow spaces of the side walls.

At this stage of assembly the display structure has the form shown in Figure 5, and it is only necessary to secure the outer bottom flaps 37 to the back surface of the main panel 12. For this purpose the structure is pref erably inverted as shown in Figure 6 and pin clips or other suitable securing elements are inserted through the outer bottom flap into the main panel as shown at 30 in Figure 6.

The display structure is then complete and may be suspended in any convenient manner. For this purpose a cord may be attached to inserted pin clips which also serve as fastening elements or further pin clips may be inserted as shown at 30' to which a cord for suspending the display may then be attached.

Figure 7 illustrates a typical layout which lends itself to shortening, in the event the space available for the display is insufficient to accommodate the full length. As an example may be mentioned a display having a total length L of 60 inches which by suitable trimming may be reduced to a length l of approximately 40 inches by elimination of the end portions of the display while yet preserving the principal message.

The assembled display is of great rigidity and of light weight as can readily be seen from the fact that a display frame measuring 30 by 60 inches and having a depth of 2 /2 inches may be made to have a weight not to exceed 16 ounces. The display is readily set up by unskilled persons and can easily be recollapsed and reassembled if desired.
